Letters Patent No. 88,834, dated April 13, 1869.

IMPROVED vrsn.

' The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom t may concern:

Be it known that I, J. D. BECK, of Liberty, in the county of Tioga, andState of Pennsylvania, have in,- vented a new and improved Vise; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specication, in which- Y Figure l is a verticalsection of my improved vise, taken through the line x z, fig. 2.

Figure 2. is a top or plan view of the same.

Figure 3 is a detail view of the adjustable plate for holding bevelledwork.

Figure 4 is a detail viewv of the plate for holdin curved, or irregularwork.

Similar letters of reference indicate corresponding parts.

My invention has for its object, to furnish an improved vise, whichshall be so constructed and arranged,

as to securely'hold irregular bevelled or plain work, and which shall,at the same time, be simple in construction, and easily adjusted; and

It consists in the construction and combination of the various parts, ashereinafter more fully described.

A represents the bench.

B is the bed-plate of the vise, which is securely bolted to the bench A.

G is the stationary jaw, which is cast solid with the bed-.plate B, andthrough which, and through a groove in the upper side of the'bed-plateB, slides the extension-bar D. l

The extension-bar D is made hollow, or is chambered longitudinally uponits under side, to receive the screw E, the nut F, and the guide-socketG.

The screw E is operated by a lever, e, in the ordinary manner, and isswivelled to the forward end of the extension-bar D,'by a screw, 82,'theforward end of which enters a circular groove around the neck of saidscrew,'as shown in g. l.

The nut F, through which the screw E passes, is set ina socket in thegroove in the bed-plate B, where it is secured in place by the bolts f1f2, as shown in iig. l.

The socket G, which is designed to serve as a guide and guard to thescrew E, may be securely bolted to the bed-plate B, or may be cast solidwith said bedplate, as may be desired, or convenient, and is providedwith bearing-places, g', upon which the extension-bar D slides, so as toprevent side-strain, or twist in operating the said bar D.

H is the movable jaw, which is pivoted to the forward part of theextension-bar D, by the bolt I and nut J, said bolt passing up throughthe said bar D, and throughthe forwardly-projecting end of the baseofthe movable jaw H.

The nut J is kept from being turned off whenl moving the jaw H about thepivoting-bolt I, hy the small screw j which passes in through the saidnut, and the end of which presses against the said screw, as shown infig. l.

The jaw H is made to carry the bolt I with it, in its movement, by thesmall screw jz, which passes in through the forward-projecting end ofthe base ofthe jaw H, and its forward end enters a longitudinal groovein the said bolt I, thus preventing the turning of the said bolt in thesaid jaw, while allowing the bolt to be tightened by operating the nutJ.

K is a pin, which passes down through a hole in the outwardly-projectingpart of the movable jaw H, and enters a hole in the upper side of theextension-bar D,

so as to hold thejaw H parallel with the jaw G, when points, to hold thework, and which are secured to said jaws by screws.

M is a plate, the rear side ofwhich, that rests against the jaw of thevise, is rounded oli', so as to rockl upon the said jaw, and is slotted,so that the face-points of the jaw may not interfere with its movements.

'Ihe upper part of the plate M is slotted, to receive the pin m1, whichpasses through a hole in the steel face L, and through a rubber block N,placed in a recess in the vise-jaw, and secured in place by the steelplate L, so as to hold the said pin securely, and prevent it fromworking out. The lower end of the plate M is notched, to it, rest, andride upon the extensionbar D.

O is a bar, which enters andslides back and forth in a groove in thevise-jaw, above the extension-bar D, and having a notch in the uppersideof its outer end, to receive a pin, m2, attached to ears upon the rearside of the lower part of the said plate M, as shown in figs. I and 3. 4

P p is a pin and spring, similar in construction and use to the pin Kk', and which, when forced down, enters holes in the bar O, to hold theplate M in a vertical position, and to hold the said bar in place whenthe plate M has been removed, and the bar O pushed fully in, so as to beout of the way.

Q is a screw, passing down throu h a hole in the rear part of the vise-jaw, so that itsl orward end may rest upon the bar O, and secure it inplace in whatever position it may be.

The screw Q, is operated by means of a leven-q, passing through itshead, as shown. j

The platevM is designed for use in holding bevelled work, and when soused, a similar plate should be attached to each-of the vise-jaws. Theplates M are automatic, and ladj ust themselves to the bevel of the workto be held. For holding thin bexelled work, the work is pushed downbetween lthe plates to the bar D. The plates M are then adjusted, andsecured by the. screws Q. rlhe work may then be raised, and securedbetween the plates, with as shallow a gripe as may be desired, and willhe held securely-in that position.

R is a plate, the lower end of which is connected with the forward edgeof the base of the jaw H, by a guide or dowel-pin 1", which enters ahole in the said part of the said jaw,ancl the upper end of which isprovided with a p in, lr2, which passes through a hole in the steelplate L, and through the rubber block N, as Yshown in fig. l. The upperpart of the plate R is enlarged, as shown in figs. l and 4, and isrecessed, to

lreceive the three slides S, and two levers T.

The levers T are pivoted at their middle points, midway between theslides S, and their ends enter holes, or slots in the said slides S, asshown in dotted lines in figs. l and 4.

U is a spring-plate, the middle part of which is secured to the end ofthe middle slide S, by screws, and its ends are connected with the endsof the side-slides S, by bolts passing through slots in the saidspringplate U. The inner ends of the said bolts may, if desil'ed,passthrough rubber blocks placed in recesses in the said side-slides. Theplate R, and its attachments, are designed for holding curved, and otherirregular work, and when so used, a similar plate should be attached toeach jaw of the vise, the springplate U, slides S, and levers T,enabling the device to adjust itself to, and securely hold the saidirregular work. d

For holding carved, and other delicate work, rubber blocks may besecured to thc forward side of plates connected with-the vise-jaws, inthe same manner as the plate R.

Having thus described my invention, l

I claim as new, and desire to secure by Letters Patente l. Theconstruction, and arrangement together, in the manner specified, of thevertically-'adjustable plate LNI, pin ml, bar O, screw Q, pin P, andstationary jaw C, as and for the purpose vset forth.

2. The construction, and arrangement together, in the manner specified,of plate R, slides S, levers T, spring-plate U, pin r2, and movable jawH, as and fer the purpose specified.

3. The arrangement, on the jaws, of the face-plates as described, tohold the plates R and M in position.
